47RE Billet Pistons

The pistons inside your Ram 5.9L Cummins' 47RE transmission are critical for its shifting and basic operations, but the stock pistons aren't quite strong enough to handle the immense levels of horsepower and torque than your big Ram can churn out with relatively few modifications. The stock pistons can warp, crack, or completely break when put under enough load and leave you and your Ram Cummins build stranded. 47RE billet pistons are far stronger than the factory cast pistons, allowing them to handle extremely high levels of horsepower and torque without letting your truck down. These 47RE pistons are CNC machined out of either billet aluminum or billet steel which can withstand the load your 5.9L Cummins is throwing down much more effectively than stock.
